Having COPD often means you can run into some difficulties in everyday life, just doing normal things like eating or sleeping. It can be hard to anything when you can't catch your breath, or when the simplest things get you winded.
There are some ways around these issues, however, and you can use them to adapt and cope.

This can happen because your stomach is pushing up against your lungs, which are likely enlarged slightly from being damaged. Even if they aren't enlarged but you're out of breath, eating can make you feel even more out of breath because as you eat, your stomach is pressing against your diaphragm.
